media: atomisp: Remove custom ATOMISP_IOC_G_SENSOR_MODE_DATA ioctl

This ioctl returns a number of fixed sensor parameters +
a number of mode-specific parameters.

With libcamera these fixed parameters are instead stored in a table
with sensor-name to parameters mappings (camera_sensor_properties.cpp);
and the variable parameters can be derived from the set fmt.

So this custom ioctl is not necessary; and it currently has no users.

Remove the ioctl and all the sensor drivers xxxx_get_intg_factor()
helpers which return this info.

This is part of a patch-series which tries to remove atomisp specific /
custom code from the sensor drivers, with as end goal to make the atomisp
drivers regular camera sensor drivers.
